The present disclosure describes systems and techniques directed to optical image stabilization movement to create a super-resolution image of a scene. The systems and techniques include a user device (102) introducing (502), through an optical image stabilization system (114), movement to one or more components of a camera system (112) of the user device (102). The user device (102) then captures (504) respective and multiple frames (306) of an image of a scene, where the respective and multiple frames (306) of the image of the scene have respective, sub-pixel offsets of the image of the scene across the multiple frames (306) as a result of the introduced movement to the one or more components of the camera system (112). The user device (102) performs (506), based on the respective, sub-pixel offsets of the image of the scene across the respective, multiple frames (306), super-resolution computations and creates (508) the super-resolution image of the scene based on the super-resolution computations.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method as recited by claim 1, wherein introducing the movement to the one or more components of the camera system is in response to entering a viewfinder mode.
3. The method as recited by claim 1, wherein introducing the movement to the one or more components of the camera system is in response to receiving a capture command.
4. The method as recited by claim 1, wherein introducing the movement to the one or more components of the camera system of the user device includes introducing an in-plane movement to the one or more components of the camera system, wherein the in-plane movement is a movement contained in a plane defined by two axes.
5. The method as recited by claim 1, wherein introducing the movement to the one or more components of the camera system of the user device includes introducing an out-of-plane movement to the one or more components of the camera system, wherein the out-of-plane movement is a movement outside a plane defined by two axes.
7. The method as recited by claim 6, wherein performing the super-resolution computations includes analyzing an influence of motion blur across the multiple frames.
8. The method as recited by claim 7, wherein performing the super-resolution computations uses a frame-recurrent approach that uses, from the multiple frames, a previous low-resolution frame and a current low-resolution frame to create a current super-resolution image.
9. The method as recited by claim 8, wherein additional or supplemental movement is introduced to the one or more components of the camera system based on a coverage score that is computed through a sampling of the multiple frames of the image of the scene.
11. The user device as recited by claim 10, wherein the user device further comprises one or more motion sensors that detect the static motion condition or the dynamic motion condition.
12. The user device as recited by claim 10, wherein the detection of the static motion condition causes the user device to introduce, through the optical image stabilization system and to one or more components of the camera system, an unsynchronized optical image stabilization movement.
13. The user device as recited by claim 10, wherein the detection of the dynamic motion condition causing the user device to introduce, through the optical image stabilization system and to one or more components of the camera system, the synchronized movement is effective to superimpose the synchronized optical image stabilization movement on a first movement, the superimposing being constructive or destructive.
14. The method as recited by claim 10, wherein the introduction of the movement to the one or more components of the camera system is in response to receiving a capture command.
17. The computer-readable storage media as recited by claim 16, wherein the super-resolution computations include computations to analyze the influence of motion blur across the multiple frames.
18. The computer-readable storage media as recited by claim 17, wherein the instructions include instructions that direct the user device to use, from the multiple frames, a previous low-resolution frame and a current low-resolution frame to create a current super-resolution image.
19. The computer-readable storage media as recited by claim 15, wherein the instructions to introduce additional or supplemental movements to the one or more components of a camera system are based on a coverage score of the multiple frames of the image of the scene.
20. The computer-readable storage media as recited by claim 19, wherein the instructions include instruction to compute the coverage score based on a sampling of the multiple frames of the image of the scene.
